I go shopping with our child or my DH goes shopping with our child (depending on my medical situation at the time). I ALWAYS make sure DS goes with us to the farm/drop point to get our items that we get from them. For my son (not always for us, though now more so) it is very important to know where things come from. He proudly says what food comes from the farmer when asked. He also knows what a napa cabbage is (he is 4, I know adults that don't know what a napa cabbage is!). I think this will become even more important as he gets older. So yes, this next baby will go to the grocery store every time too.

DH I could leave at home. When we go shopping as a family, the budget goes up. This is because of DH not DS.
